...with a graduate student named George Volkoff, argued that neutron stars could in fact exist. They would have a diameter of about 10 km (6 miles) and weigh about 10 million tons per cu. cm. In the second paper, innocuously titled "On Continued Gravitational Contraction," Oppenheimer and another student, Hartland Snyder, contended that if the dying star was massive enough, nothing in Einstein's theory stood in the way of the ultimate compression?the formation of a singularity...

...1930s, the theoretical physicist J. Robert Oppenheimer and one of his graduate students at the University of California, Hartland Snyder, proposed what seemed like a wildly improbable idea. When the nuclear fires of extremely massive stars die out, they suggested, the stars collapse so completely under the pull of their own gravity that they literally crush themselves out of existence, leaving only a "black hole" in space as evidence of their passing. Now, just as scientists are beginning to study the first tentative signs that there really may be such black holes (TIME, April 5), they are also being asked...
First postulated in 1939 by Physicist J. Robert Oppenheimer and Hartland Snyder, one of his graduate students at the University of California at Berkeley, black holes are the theoretical residue of extremely massive stars whose thermonuclear fuel has been exhausted. As the fires go out, the gases-which have been supported in the shape of a huge, distended globe by heat and radiation -suddenly begin to fall inward toward the star's center of gravity. If the star is massive enough, the imploding gases gather such momentum as they fall that they virtually crush themselves out of existence...
